i like to understand this formulas y + u = x

Question

solve for in y of the other variables

Answer 1

You are given the following equation:     y + u = x     <==>     x = y + u

Looking at the equation, we see that it is solved for x in terms of the other variables, y and u, since it basically states that x is equal to the sum of y and u.

To solve this equation for y in terms of the other variables, x and u, we need to isolate the y variable to one side of the equation by moving all other variables to the other side of the equation.

     y + u = x          to solve for y, subtract u from both sides of the equation

     y + u - u = x - u

     y + 0 = x - u

     y = x - u
